Title: Method for measuring deterioration degree of polypropylene resin molded product
Inventor: KAWAMURA KENICHI
IPC: G01N25/22
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To make measurable a deterioration degree within a shorter time without using a special apparatus by replacing a nitrogen atmosphere having a sample allowed to stand therein and raised to a predetermined holding temperature with an oxygen atmosphere to isothermally hold the sample at the holding temp. and measuring the oxidation induction period up to the appearance of the heat generating peak of the sample. SOLUTION: A predetermined amt. of a sample formed into a powdery matter by finely grinding a polypropylene resin molded product being an object to be measured is allowed to stand in a nitrogen atmosphere and this nitrogen atmosphere is heated to a predetermined temperature at a constant speed. Thereafter, the nitrogen atmosphere is replaced with an oxygen atmosphere to isothermally hold the oxygen atmosphere to the holding temp. and, after while, the sample is oxidized to generate exothermic reaction. When a time is further elapsed, oxidation becomes violent to generate the peak of exothermic reaction. The time up to the appearance of the exothermic peak is measured as an oxidation induction period and this oxidation induction period is used as the measure of a deterioration degree. The holding temperature is set so that the oxidation induction period becomes 60-100 min.

Filed: 1985-10-21
Abstract: PURPOSE:To make it possible to always obtain good printing quality regardless of the stiffness degree of paper, by constituting the titled printing apparatus so that the center of the heat generator of a thermal printing head comes to a paper discharge direction from the extended line of the straight line connecting the release point of a platen in a non-printing state and the paper wound around the platen in a paper discharge side and the center of the platen. CONSTITUTION:The center B of the heat generator of a thermal printing head 2 is set so as to reach a position transferred by about 1mm from the line connecting the center A of a platen 1 and a point 10 where paper 4 is released from the outer periphery of the platen to a paper discharge direction (D-direction) side. Because plain paper has weak stiffness, a plane part 1a is formed to the outer peripheral surface of the platen 1 by the pressing force F of the thermal printing head 2 and a heat generating resistor 2a applies printing to the paper 4 through a film ribbon 3a within said plane part. Next, because the pressing force F of the thermal printing head 2 to paper having strong stiffness such as a postcard is diffused to the contact part with the paper and the peripheral part thereof, the outer periphery of the platen 1 slightly deforms but the heat generating resistor 2a is certainly pressed to the paper 4 through the film ribbon 3a by the strong stiffness of the paper.

Filed: 1985-10-21
Abstract: PURPOSE:To provide the blanking metal die which can prevent the floating of a slug causing a defective dent to be obtd. by providing the specified groove on the inner side face of a die. CONSTITUTION:The groove 8 in the same width reaching to the surface of the opposite side from a blanking surface 7 is provided on the one inner side face 6 of a die split block 5 for instance. The groove 8 is inclined by the prescribed angle theta for the blanking direction 9 of the punch moving direction. The slug is thus not floated up even with the ascent of the punch because of the projecting part of the slug corresponding to the shape of the groove 8 coming out of the groove 8 and being hanged slightly on the face 6 or the slug being brought in contact with the inner side surface in the lateral direction by being pushed by the groove 8. The defective dent of a blanked product can therefore be eliminated in blanking a lead frame, etc.
